One-Loop Yang-Mills Integrands from Scattering Equations (1910.03602v2)
Published 8 Oct 2019 in hep-th, gr-qc, and hep-ph
Abstract: We investigate in the context of the scattering equations, how one-loop linear propagator integrands in gauge theories can be linked to integrands with quadratic propagators using a double forward limit. We illustrate our procedure through examples and demonstrate how the different parts of the derived quadratic integrand are consistent with cut-integrands derived from four-dimensional generalized unitarity. We also comment on applications and discuss possible further generalizations.
